Abstract:

Given a set P of n points in the Euclidean plane, consider the convex polygons determined by subsets of P. We show that the problem of selecting the kth largest-area convex polygon is NP- hard by a reduction from the problem of finding the kth largest m-tuple [3] determined by m sets X 1,X2, . . . ,X,,,. The problem of finding the convex polygon with kth largest area was introduced by Chazelle [1] as an example of a multidimensional selection problem for which the time complexity of selecting the median seems inherently difficult.
